Question

# If then

Hint:

### The angles of the triangle ABC are denoted by A, B, C and the corresponding opposite sides by a, b, c. solve If then angle.

## The correct answer is:

### If then

**All three sides are equal**. All three angles are congruent and are equal to 60 degrees. It is a regular polygon with three sides. The perpendicular drawn from vertex of the equilateral triangle to the opposite side bisects it into equal halves.
